Hair Loss Compositions and Methods of Making and Using Same

ABSTRACT

A composition for promoting hair growth comprises hinoki oil, red clover extract, and a peptide. The hinoki oil can comprise from about 0.01% to about 5% by weight of the composition, the red clover extract can comprise from about 1 ppmw to about 1,000 ppmw of the composition, and the peptide can comprise from about 0.01 ppmw to about 500 ppmw of the composition.

BACKGROUND

This disclosure relates to methods of hair loss treatment. More specifically, it relates to compositions and methods for inhibiting hair loss and/or stimulating hair growth.

Hair loss, also known as alopecia, affects both males and females, and may be caused by genetic factors, auto-immune disorders, chemotherapy, aging, local or systemic disease, etc. None of the conditions causing alopecia are very well understood, however such conditions are generally distressing to the individual experiencing them, in part due to the human physical appearance often being regarded as an essential factor in social communication and interactions. Consequently, some individuals experiencing alopecia can perceive hair loss as a social handicap.

Alopecia may occur in various parts of the human body, such as scalp, face, limbs, and trunk, and may be generally grouped in the following categories: male or female pattern baldness (e.g., androgenic alopecia), toxic alopecia (e.g., hair loss due to chemotherapy), alopecia aerata (i.e., hair loss occurs in demarcated areas), and scarring alopecia (e.g., hair loss due to inflammation and tissue destruction). Androgenic alopecia is one of the most common causes of hair loss and it occurs due to a deficiency in androgenic metabolism, e.g., accumulation of dihydrotestosterone (DHT) in hair follicles owed to a defective regulation in an enzyme responsible for DHT synthesis, 5α-reductase. Some current hair loss treatments involve the use of 5α-reductase inhibitors for modulating the levels of DHT in the hair follicles. However, such 5α-reductase inhibitors result only in moderate regrowth of hair in less than half of the users.

Some hair loss treatment formulations involve the use of an alcohol-based delivery vehicle, which may pose various problems. Before the hair loss treatment becomes effective, the alcohol present in the hair treatment formulation may cause the hair of the individual using it to become brittle, break and/or fall out. Alcohol based delivery vehicles may also lead to the irritation of the scalp, and as a result some people may discontinue the use before seeing the potential beneficial effects from the hair loss treatment.

As such, there exists a need for improved hair loss treatment compositions and methods of using same.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter that form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.

DETAILED DESCRIPTION

It should be understood at the outset that although an illustrative implementation of one or more embodiments are provided below, the disclosed systems and/or methods may be implemented using any number of techniques, whether currently known or in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques below, including the exemplary designs and implementations illustrated and described herein, but may be modified within the scope of the appended claims along with their full scope of equivalents.

Hair is composed of a strong structural protein called keratin. Hair forms in a pouch-like structure below the skin called a hair follicle, which encloses the hair root. Visible hair, such as scalp hair for example, is the hair shaft, which is keratinized, hardened tissue that grows from the hair follicle. At the base of the follicle is the dermal papilla. The dermal papilla is fed by the bloodstream which carries nourishment to produce new hair. The dermal papilla plays a crucial role in the dermal-epidermal interactions and is of great importance for the hair formation and growth cycle.

The growth and development of hair follicles is influenced by a number of different growth factors and cytokines, such as members of the fibroblast growth factor (FGF) family and endothelial growth factors (EGF) family, e.g., vascular endothelial growth factor (VEGF).

Throughout the life of an individual, hair growth and hair renewal are determined by the activity of the hair follicles. Normal hair follicles cycle between a growth stage (anagen), a degenerative stage (catagen), and a resting stage (telogen), which are each characterized by very specific molecular and cellular mechanisms. Scalp hairs have a relatively long life cycle: the anagen stage ranges from 2 to 6 years, the catagen stage ranges from a few days to a few weeks, and the telogen stage is approximately three months. Shorter hairs found elsewhere on the human body have corresponding shorter anagen durations. The morphology of the hair and the hair follicle changes dramatically over the course of the life cycle of the hair.

During the anagen phase the hair follicle is highly active metabolically. The follicle comprises a dermal papilla at the base of the follicle; and epidermal matrix cells surrounding the dermal papilla form the base of the hair shaft, which extends upwards from the papilla through the hair canal. The matrix cells are the actively growing portion of the hair. The cells of the dermal papilla “send” signals to the matrix cells, which then migrate to the hair follicle matrix. In this region, the cells of the dermal papilla emit additional signals which allow the matrix cells to proliferate and then to differentiate, further allowing the elongation of the hair shaft. During the anagen phase, the hair follicle migrates through the dermis so as to be anchored in the hypodermis in contact with the adipose tissue.

At catagen, the matrix cells retract from the papilla, and other degenerative changes occur. For example, the vessels and capillaries supplying blood and nutrients to the hair follicle shrivel and stop functioning. A column of epithelial cells pushes the keratinized proximal shaft of the hair upwards and cell death occurs within the follicle. The cells of the lower part of the hair follicle enter into apoptosis, thus allowing degeneration of the hair follicle. The hair shaft is then shed from the scalp or other part of the body as the hair follicle enters telogen, the resting stage of the hair growth cycle. Telogen is a lag phase characterized by inactivity of the hair follicle and loss of the hair before a further entry into the anagen phase.

Although hair follicle regulation and growth are not well understood, they represent dynamic processes of proliferation, differentiation, and cellular interactions during tissue morphogenesis. It is believed that hair follicles are formed only in the early stages of development and are not replaced. Thus, an increase in damaged or non-functioning hair follicles is generally associated with hair loss. It is further believed that hair growth may be restored to a dormant and/or damaged hair follicle, but may generally not be restored to a follicle that has fully ceased functioning (e.g., a follicle that has died).

Disclosed herein are embodiments of hair loss treatment compositions comprising hinoki oil, red clover extract, a peptide and a carrier base fluid. In an embodiment, the composition may be used for inhibiting scalp hair loss and/or stimulating scalp hair growth. In some embodiments, the composition may be used for inhibiting facial hair (e.g., eyelashes, eyebrows, etc.) loss and/or stimulating facial hair growth. In other embodiments, the composition may be used for inhibiting hair loss and/or stimulating hair growth in other body areas, e.g., limbs, trunk, etc. Hereinafter, the disclosure will collectively refer to the use of Compositions for the Treatment of Hair Loss, designated a CTHL, with the understanding that while a particular focus of the present disclosure is the treatment of the scalp, such focus is non-limiting and a CTHL of the type disclosed herein may be used in the treatment of hair loss on any applicable body area. The CTHLs may be applied/administered to the body and used to treat hair loss, for example providing for both the inhibition of hair loss and the stimulation of hair growth. Each of the components of the CTHL as well as methods of using same will be described in more detail herein.

In an embodiment, the CTHL comprises hinoki oil or any fraction or portion of the hinoki oil (e.g., one or more components of the hinoki oil). Hinoki oil or white cedar oil is an essential oil usually obtained by steam distillation of the wood from the tree Chamaecyparis obtusa, which is a white cedar or conifer from a cypress family native to northeast Asia.

Hinoki oil is believed to modulate the expression of VEGF, and an increased VEGF production may aid in providing higher blood flow to hair follicles by enhancing angiogenesis (i.e., blood vessel formation) in the areas surrounding the hair follicles. Without wishing to be limited by theory, VEGF is believed to be a positive regulator of hair growth, i.e., the higher the VEGF levels, the higher the number of blood vessels supplying the hair follicle, the more enhanced the hair growth effect.

In an embodiment, the hinoki oil may be included within the CTHL in any suitable and/or therapeutic amount. In an embodiment the hinoki oil of the type disclosed herein may be present within the CTHL in an amount of from about 0.01 wt. % to about 10 wt. %, alternatively from about 0.02 wt. % to about 5 wt. %, or alternatively from about 0.05 wt. % to about 0.4 wt. %, based on the total weight of the CTHL.

In an embodiment, the CTHL comprises red clover extract. Red clover (i.e., Trifolium pratense) is a perennial herb that commonly grows wild in meadows throughout Europe and Asia, and has now been naturalized to grow in North America. The red flowers at the end of the branched stems of the clover plants may be used for the preparation of red clover extracts with an elevated content of isoflavones (e.g., biochanin A, formononetin, genistein, genistin, daidzein, daidzin, pratensein, pectolinarigenin, calycosin, trifoside, etc.). Without wishing to be limited by theory, isoflavones or phytoestrogens are plant-based compounds that produce estrogen-like effects in the human body. Red clover is available in a variety of preparations, including teas, tinctures, tablets, capsules, liquid extracts, and red clover extracts standardized to specific isoflavone contents. Red clover extract with an elevated isoflavone content may be obtained by solvent extraction, where the solvent can be an alcohol such as ethanol.

In an embodiment, the red clover extract comprises isoflavones comprising O-methylated isoflavones. O-methylated isoflavones or methoxy isoflavones comprise isoflavones with methylations on hydroxyl (—OH) groups, i.e., methoxy (—OCH₃) groups. The presence of the methoxy groups has an effect on the solubility of the isoflavones, e.g., the O-methylated isoflavones are less soluble in water than the isoflavones with similar structure but lacking the methoxy groups. Such solubility effects on the isoflavones makes the O-methylated isoflavones good candidates for selective extraction through solvent extraction methods. Nonlimiting examples of O-methylated isoflavones suitable for use in this disclosure include biochanin A, calycosin, formononetin, pratensein, and the like, or combinations thereof.

In an embodiment, the red clover extract comprises isoflavones comprising biochanin A. Without wishing to be limited by theory, biochanin A is believed to negatively regulate dihydrotestosterone (DHT) levels, and consequently to positively regulate hair growth by inhibiting the activity of 5α-reductase, an enzyme responsible for converting testosterone to DHT. An increased level of DHT is associated with alopecia (i.e., hair loss) in men, and to some extent, in women. The inhibitory effect of biochanin A on 5α-reductase is described in more detail in J. Endocrinology (1995), volume 147(2), pages 295-302, which is incorporated by reference herein in its entirety.

In an embodiment, the red clover extract may be included within the CTHL in a suitable and/or therapeutic amount. In an embodiment the red clover extract of the type disclosed herein may be present within the CTHL in an amount of from about 0.1 ppmw to about 1,000 ppmw, alternatively from about 1 ppmw to about 500 ppmw, or alternatively from about 5 ppmw to about 250 ppmw, based on the total weight of the red clover extract.

In an embodiment, the CTHL comprises one or more peptides. While not intending to be limited by theory, a peptide may promote the production of proteins that form the matrix around the dermal papilla, e.g., extracellular matrix (ECM) proteins. ECM proteins around the dermal papilla generally favor better hair anchoring. A larger amount of ECM proteins around the dermal papilla may lead to an increased size of the hair follicle, and thus may lead to an increase in hair number and vitality. In a further embodiment, the peptide may reduce inflammation of the scalp.

Nonlimiting examples of peptides suitable for use in this disclosure include tripeptide-1, acetyl hexapeptide-8, acetyl dipeptide-1, caproyl tetrapeptide-3, carnosine, glutathione, marine oligopeptide, palmitoyl oligopeptide, human oligopeptide-1 (EGF), acetyl tetrapeptide-3, palmitoyl tetrapeptide-7, acetyl tetrapeptide-5, palmitoyl hexapeptide-14, pentapeptide-3, nonapeptide- 1, acetyl hexapeptide, hexapeptide- 11, SH-polypeptide-15, hexanoyl dipeptide-3, acetyl octapeptide-3, palmitoyl tripeptide-5, palmitoyl dipeptide-5, palmitoyl dipeptide-6, acetyl tetrapetide-2, and myristoyl pentapeptide-17, a peptide compound characterized by Formula I and/or a peptide conjugate compound characterized by Formula II, or combinations thereof:

where A represents the radical corresponding to a monocarboxylic acid of general formula R—COOH, where R represents a linear or branched C₁-C₂₄ aliphatic radical optionally substituted with a hydroxyl group. In an embodiment, such monocarboxylic acid is unsaturated. In an embodiment, the monocarboxylic acid comprises lipoic acid or its reduced form, dihydrolipoic acid, N-lipoyl lysine, retinoic acid, or combinations thereof. X represents 1 to 3 Lys residues, that are optionally methylated. In the case of Formula II, X may represent a covalent bond. Y represents a hydroxyl (i.e., —OH) or amino (i.e., —NH₂) group. The amino acids of Formulas I and II may be in the D, L or DL form. A—X may represent a hydrogen atom.

In an embodiment, the monocarboxylic acid A comprises an omega-3 acid comprising a-linolenic acid, cervonic acid, timnodonic acid, pinolenic acid, or combinations thereof. Cervonic acid, timnodonic acid and pinolenic acid are also known under the respective names: 4,7,10,13,16,19-docosahexaenoic acid (DHA), 5,8,11,14,17-eicosapentaenoic acid (EPA) and 5,9,12-octodecatrienoic acid. Alternatively, in an embodiment, the monocarboxylic acid A comprises acetic acid, myristic acid, palmitic acid, hydroxy-decenoic acids, decenoic acids, trans-10-hydroxy-Δ2-decenoic acid, trans-oxo-9-decen-2-oic acid, or combinations thereof.

In an embodiment, the peptide compounds characterized by Formulas I and/or II may be chemically or physically conjugated with the monocarboxylic acids A. The conjugated peptides may be bonded in the form of salts, esters, or amides to such monocarboxylic acids A. The amino acids in the peptides characterized by Formula I or the peptide conjugates characterized by Formula II may have a D, L, or DL configuration, i.e., such peptides may contain one or more asymmetrical carbon atoms, and thus may exist in the form of enantiomers, diastereoisomers, or combinations thereof. The peptide conjugates characterized by Formula II are low-molecular-weight derivatives which may be obtained in the form of amides of the monocarboxylic acids A.

In an additional embodiment, the peptides characterized by Formula I or the peptide conjugates characterized by Formula II may be coupled with zinc, in the form of salts, so as to form complexes.

For the purposes of the present disclosure, the term “Lys” is intended to mean lysine or a halogenated derivative of lysine, such as dihydrobromomethyllysine, the term “His” is intended to mean histidine, and the term “Gly” is intended to mean glycine or an alkylated derivative thereof, such as methylglycine.

In an embodiment, the peptides characterized by Formula I or the peptide conjugates characterized by Formula II may be obtained in the NH₂-terminal form (e.g., exhibiting an amide function), alternatively in the OH-terminal form (e.g., exhibiting a carboxylic acid function). Examples of peptides and peptide conjugates suitable for use in the present disclosure are described in more detail in U.S. Pat. Nos. 7,507,719 to Pinel et al. and 8,227,426 to Gupta et al., each of which is incorporated by reference herein in its entirety.

In an embodiment, the peptide may be included within the CTHL in a suitable and/or therapeutic amount. In an embodiment, the peptide may comprise acetyl tetrapeptide-3. In an embodiment the peptide of the type disclosed herein may be present within the CTHL in an amount of from about 0.01 ppmw to about 1,000 ppmw, alternatively from about 0.01 ppmw to about 500 ppmw, or alternatively from about 0.1 ppmw to about 100 ppmw, based on the total weight of the CTHL.

In an embodiment, the CTHL may further comprise retinyl palmitate. Retinyl (or retinol) palmitate, or vitamin A palmitate, is the ester of retinol (vitamin A) and palmitic acid, and is commonly used as a vitamin supplement for the treatment of vitamin A deficiency. Retinyl palmitate may act as an antioxidant, potentially limiting the free radical damage to the skin and scalp.

In an embodiment, the retinyl palmitate may be included within the CTHL in a suitable and/or therapeutic amount. In an embodiment the retinyl palmitate may be present within the CTHL in an amount of from about 0.01 wt. % to about 0.5 wt. %, alternatively from about 0.05 wt. % to about 0.2 wt. %, or alternatively from about 0.05 wt. % to about 0.1 wt. %, based on the total weight of the CTHL.

In an embodiment, the carrier base fluids that may be used in the CTHL include any carrier fluid or combination of excipients suitable for use in cosmetic and/or medicinal applications. For example, the CTSHL may comprise an aqueous carrier base fluid. In an embodiment, the aqueous carrier base fluid comprises deionized water.

In an embodiment, the carrier base fluid is substantially free of alcohol, i.e., an alcohol-free carrier base fluid. In such embodiment, the carrier base fluid may comprise less than about 5%, less than about 4%, less than about 3%, less than about 2%, less than about 1%, less than about 0.1%, less than about 0.01%, less than about 0.001%, or less than about 0.0001 wt. % alcohol. In an embodiment, the alcohol refers to denatured alcohol (e.g., comprising ethanol).

In an embodiment, the carrier base fluid may act as a solvent, carrier, diluent and/or dispersant for the constituents of the composition, and may allow for the uniform application of the constituents to the surface of the skin at an appropriate dilution, e.g., topical application. For example, carrier base fluids can be emulsions, lotions, creams, tonics, sprays, aerosols, and the like. The carrier base fluid may also facilitate penetration of the composition into the skin.

In an embodiment, the carrier base fluid comprises a lotion suitable for topical application. In such embodiment, the lotion may comprise carbomer, water, glycerin, isopropyl myristate, mineral oil, stearic acid, glycol stearate, cetyl alcohol, dimethicone, preservatives, triethanolamine, and the like, or combinations thereof.

The various ingredients used in the CTHL may be soluble or insoluble in the carrier base fluid. In an embodiment, all ingredients of a CTHL are soluble in the carrier base fluid, and the carrier base fluid acts as a solvent. In another embodiment, one or more of the ingredients used in the CTHL may be solubilized in a solubilizer prior to mixing in the carrier base fluid, such that these ingredients become soluble in the carrier base fluid. Nonlimiting examples of solubilizers suitable for use in the present disclosure include water, glycerin (e.g., vegetable glycerin), various esters, polyethylene glycol (PEG), derivatives thereof, or combinations thereof.

Alternatively, in an embodiment, all or some ingredients of a CTHL may be insoluble in the carrier base fluid. In such embodiment, those ingredients may be dispersed as a first step in a vehicle by means of, for example, a suspension, emulsion, gel, cream or paste, or the like, followed by a second step of introducing the vehicle into the carrier base fluid. Nonlimiting examples of vehicles suitable for use in the present disclosure include water, denatured alcohol, propylene carbonate, PEG, castor oil, ethylene glycol monobutyl ether, diethylene glycol monoethyl ether, corn oil, dimethyl sulfoxide, ethylene glycol, isopropanol, wild soybean (e.g., Glycine soja) oil, sorbitol, soluble collagen, butylene glycol, glycerin (e.g., vegetable glycerin), or combinations thereof, or other suitable various solvents that aid in penetration of the skin. Vehicles or carrier base fluids suitable for use in the present disclosure are described in more detail in U.S. Pat. Nos. 6,184,247 to Scheider and 6,579,516 to Mansouri, each of which is incorporated by reference herein in its entirety. It will be apparent to one of skill in the art, with the help of this disclosure, that the range of possible acceptable vehicles and carrier base fluids is very broad. In an embodiment, the vehicle may be present in an amount of from about 0.1 wt. % to about 10 wt. %, alternatively from about 1 wt. % to about 7 wt. %, or alternatively from about 4 wt. % to about 5 wt. %, based on the total weight of the CTHL.

The CTHL may comprise various known and conventional cosmetic adjuvants so long as they do not detrimentally affect the desired hair loss preventative or hair growth/regrowth stimulatory properties of the composition. In an embodiment, the CTHL may further comprise inactive ingredients, such as surfactants, co-solvents, and excipients or fillers (e.g., solid, semi-solid, liquid, etc.); emollients; delivery enhancers; circulation enhancers; antimicrobial agents; anti-inflammatory agents; foaming agents; carriers; diluents; binding agents (e.g., dextran); thickening agents; gelling agents; vitamins, retinoids, and retinols (e.g., vitamin B3, vitamin A, etc.); pigments; fragrances; sunscreens and sunblocks; anti-oxidants and radical scavengers (e.g., tocopheryl acetate or vitamin E acetate); organic hydroxy acids; exfoliants; skin conditioners (e.g., ethylhexylglycerin, hydrolyzed soy protein, glycol distearate, cyclopentasiloxane, quaternium-79 hydrolyzed keratin, propylene glycol, etc.); moisturizers; humectants (e.g., hydrolyzed soy protein, propylene glycol, etc.); ceramides, pseudoceramides; phospholipids, sphingolipids, cholesterol, glucosamine; pharmaceutically acceptable penetrating agents (e.g., n-decylmethyl sulfoxide, lecithin organogels, tyrosine, lysine, etc.); preservatives (e.g., phenoxyethanol, benzoic acid, dehydroacetic acid, polyaminopropyl biguanide, DMDM hydantoin or 1,3-bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione, iodopropynyl butylcarbamate, iodopropynyl butylcarbonate, stearalkonium chloride, etc.); amino acids such as proline; pyrrolidone carboxylic acid, its derivatives and salts; saccharide isomerate; panthenol (i.e., provitamin of B₅); buffers together with a base such as triethanolamine or sodium hydroxide; waxes, such as beeswax, ozokerite wax, paraffin wax; plant extracts, obtained from plants such as Aloe vera leaf, cornflower, witch hazel, elderflower, green tea (e.g., Camellia sinensis) leaf, grape (e.g., Vitis vinifera) seed, jojoba (e.g., Simmondsia chinensis) seed, tea tree (e.g., Malaleuca alternifolia) leaf, rosemary (e.g., Rosmarinus officinalis), henna, sunflower (e.g., Helianthus annuus) seed, wild soybean (e.g., Glycine soja), argan tree kernel or argan, cucumber, shiso, etc.; or combinations thereof. As will be appreciated by one of skill in the art viewing this disclosure, the amount of optional ingredients may be varied depending upon the intended application of the CTHL, and in various embodiments a suitable and/or therapeutic amount may be included in the CTHL.

In an embodiment, the plant extracts used in the CTHLs may be obtained from any commercially available source. For example, hinoki oil , tea tree oil, and rosemary oil may be purchased from Liberty Natural Products of Oregon City, Ore., and grape seed oil may be purchased from MakingCosmetics Inc. of Renton, Wash.

Alternatively, in an embodiment, the plant extracts used in the CTHLs may be obtained using any suitable known extraction method. For example, in an embodiment, a plant extract (e.g., green tea extract, red clover extract, etc.) can be produced/obtained by extracting a plant or a plant portion (e.g., leaf, flower, stem, etc.) with an organic solvent. Nonlimiting examples of organic solvents suitable for use in the present disclosure include hexane, ethyl acetate, ethanol, hydro-ethanol, denatured alcohol, and the like, or combinations thereof.

Alternatively, in an embodiment, a plant extract may be produced by solvent sequential fractionation. For example, by using this technique, a plant or plant portion (e.g., leaves and stems of a shiso plant) may be sequentially extracted with hexane, ethyl acetate, ethanol, and hydro-ethanol. The extracts obtained after each step (i.e., fractions) of the sequence will contain chemical compounds in increasing order of polarity, similarly to the solvents used for extracting them, e.g., the least polar compounds will be extracted in hexane, followed by ethyl acetate, and the most polar compounds will be extracted in hydro-ethanol. Without wishing to be limited by theory, hydro-ethanol is a mixture of ethanol and water, which has a higher polarity than ethanol due to the fact that it contains water, which is inherently more polar than ethanol. The fractions produced by solvent sequential fractionation may be dried to evaporate the solvents, resulting in a plant extract (e.g., shiso extract). It will be apparent to those of skill in the art with the help of this disclosure that many other solvents can be used in practicing the solvent sequential fractionation extraction of any of the plant extracts used in the CTHLs.

Alternatively, in an embodiment, a plant extract may be produced by total solvent extraction techniques (e.g., total hydro-ethanolic extraction techniques). Generally, this technique may be referred to as a lump-sum extraction of a material of interest, for example lump-sum extraction of red clover leaves. The extract generated by total solvent extraction techniques may contain a broad variety of phytochemicals present in the material to be extracted, including fat soluble compounds and water soluble compounds. Following collection of the plant extract, the solvent (e.g., hexane, ethyl acetate, hydro-ethanol, etc.) may be evaporated, resulting in an extract that may be used in the CTHLs.

Alternatively, in an embodiment, a plant extract may be produced by total ethanol extraction. This technique also uses plant material to obtain the extract of interest, but ethanol, rather than hydro-ethanol, is the solvent. This extraction technique generates an extract that may include fat soluble and/or lipophilic compounds in addition to water soluble compounds. Following collection of the plant extract, the solvent (e.g., ethanol) may be evaporated, resulting in an extract that may be used in the CTHLs.

Alternatively, in an embodiment, a plant extract may be produced by supercritical fluid carbon dioxide extraction (SFE). In this extraction procedure, a plant material containing an extract of interest is not exposed to any organic solvents.

In an embodiment, more than one form of CTHL may be applied to the hair, for example, in one treatment session, alternatively in different treatment sessions, the CTHL may be topically applied to the scalp as a shampoo, conditioner, scalp stimulator foam, or combinations thereof.

The CTHLs may be added in a CTHL concentrate form as previously described herein to any shampoo, conditioner, styling product, or any other suitable hair care formulation that is commercially available or commonly used. For example, a CTHL concentrate may be mixed with fatty acid esters or sorbitol and sorbitol anhydrides (e.g., polysorbates). These compounds have nonionic properties that inhibit shedding of hair. Without wishing to be limited by theory, polysorbates are nonionic surfactants obtained by esterification of sorbitol with one or three molecules of a fatty acid (e.g. stearic, lauric, oleic, palmitic, etc.).

In an embodiment, the CTHL may be topically administered at least on a daily, and preferably a twice daily, basis for a period of time sufficient to bring about the desired level of improvement in modulation of hair growth or regrowth. For example, a user may topically administer the CTHL directly to a balding area or other area where increased hair growth is desired by gently massaging the composition of the present invention into the desired area. This process may be repeated later the same day. In an embodiment, the CTHL may be left on the scalp or other area where increased hair growth is desired between applications occurring on the same day or on different days.

In an embodiment, the topical application of the CTHL may continue for any suitable period of time. For example, within a few weeks to a few months of the initial application, a user may notice a reduction in hair loss and/or an increase in hair growth or regrowth. It should be appreciated that the frequency with which the CTHL should be applied will vary depending on the desired effect. In particular, the degree of cosmetic enhancement might vary directly with the total amount of CTHL used.

In an embodiment, disclosed herein is a method of treating a skin or a hair condition comprising administering a composition to dermal papilla cells of a subject, wherein the composition comprises hinoki oil, red clover extract, and a peptide; and increasing a growth factor from the dermal papilla cells of the subject in response to administering the composition.

As will be appreciated by those of skill in the art with the help of this disclosure, other methods may be used to topically apply/administer the CTHLs described herein.

In an embodiment, a composition for the treatment of hair loss such as CTHL may be advantageously used to diminish hair loss and/or promote hair growth and/or regrowth. For example, as disclosed herein, a composition for the treatment of hair loss such as CTHL may diminish and/or stop hair loss in a time period of from about 7 days to about 80 days, alternatively from about 10 days to about 28 days, or alternatively from about 14 days to about 21 days.

While not intending to be limited by theory, it is believed that the CTHL may advantageously regrow hair in a time period of from about 4 weeks to about 20 weeks, alternatively from about 6 weeks to about 16 weeks, or alternatively from about 8 weeks to about 12 weeks.

In some embodiments, the CTHL may advantageously diminish and/or stop the itching of the scalp when a CTHL is topically applied to the scalp, which may be due in some embodiments to the use of an alcohol free carrier fluid along with one or more optional ingredients

In an embodiment, the CTHL may advantageously promote hair growth from dormant and/or injured hair follicles, e.g., the CTHL may have a rejuvenating effect on the hair follicles. However, if the hair follicle is dead, it is believed that the hair follicle cannot become functional again. Additional advantages of the CTHL and methods of using same may be apparent to one of skill in the art viewing this disclosure.
